-IMPROVEMENT IN ELECTRO-MAGNETIC BURGLAR-ALARMS.

Specification forming part of Letters Patent No. 206,182, dated J ul y '23, 1878 application tiled Muy 24, 1878.

To all Jwhom it may concern: I

Be it known that LMAX KoLosEUsmf New VYork city, in the county of New York and State and it consists in a certain construction and arrangement'of safes or vaults, in connection with magnetic or elect-ric wires, a battery, and an .alarm apparatus, by which the drilling, forcible breaking, or opening, as well as removal, of safes is prevented, in connection .with an insulating compositionor plates, all

of which will be more fully described hereinafter, reference being had to the accompany- Iing drawing and the letters of reference Vmarked thereon. i'

Inthe aecompanying4 drawing, Figure 1 rep.- resents asafe incomiection with Ysuitable circuit-wires', battery, andalann. .'Fig. 2 .is an interior view of the safe-donn# Fig. 3 is an enlarged sectional detail'vlew of the same.

In the drawing, A represents a safe, constructed of alternate layers of chilled iron or steel, a., insulating plate or composition, b, Airon .or steel plate, cl insulating composition, d,'iill ing of plaster',c, and kinner liningof wood or` iron, f. Y I

The insulating composition is composed of water glass, alum, powdered burned clay, fresh or unburned clay, and borax, in certain proper qua-ntiies; and this composition is an important fea ure of my invention. I. The safe is placed upon metal plates B C, which are 1ct into the iioor, and to which the circuit-wires g h are connected that lead to an alarm apparatus, D, of the ordinary construe tion. To the central part of the safe, at the' bottom, is attached a wire,.', which also leads tothe alarm apparatus. This ymay be placed .in any suitable place about the house, ,0r it may be arranged yat the police-station, or any other place`desired,where the alarm is to be given, it' the safe is tampered with in any manner. At any desired place maybe arranged suit- .able relays E, and these are connected to cirspring-bolt, .k, protected by rubber, horn, or

other non-conducting material, and only when the door is opened or tampered with will the apparatus be started bythe connect-ion or circuit becoming broken as the bolt is thrown back by the spring l. The circuit-wire g, connecting with the roller-plate C, 0r other outside part of the safe, leads to the connectingpiece F, as well as to the alarm apparatus, and the wire h connects with the roller-plate B,`through the relay E, to battery H, by which the latter is closed with the wire g, and the circulating current holds the anchor in contact with the relay.

To save theV battery 'as much as possible, a current-breaker, G, is interposed between thc relay E and the battery, by which the circuit is opened during the day-time. Any other insulating material may be used, however, instead of the one described above. Instead of the plate, a pin, tube, or screw may be employed and the wires connected thereto.

The object of 'arranging the relay E in the manner shown and described is to form a c`ir cuit with the safe or vault, `the batteryand the alarm apparatus. The anchor l of the relay is held in contact bythe electric current through the wires h and g, and in case'any of the wires are cut or the vault is moved, the current will be broken, the anchor of the relay falls o, and closes by this the side current through thewire k, which then sets the alarm apparatus in motion. s

The composition consists of one part ground alum, two partsburned clay, one part unburned clay, one-fourth part borax, .all mixed with proper proportion of water-glass.

It will be readily understood that the moment it is attemptedto drill or break a hole into the safe, when the drill comes iu contact ,with the isolated plate e ,through the insulating composition, the alarm apparatus is started, and will keep on rin ging unti'l released by the proper person; or, if a key is in1roduced into the key-hole, the connection is formed and the' alarm' apparatus will commence to ring; or, if the safe should be moved from the plates upon which it stands or any of the connecting-wires are cntz the circuit is lbroken and the alarm apparatus 1s started.

Thus it will be seen, :no matter'w-hat it is intended to do with or to the safe, the alarm apparatus is always set in operation, and will re main so until it iareleased.

The great advantages of my improvement are, that it'is very simple inl its construction; it can be very readily applied to any 'safe or place of deposit for valuables; it is positive and sure in its operation; it can be nrnshed at a very moderate cost; it is notlia le to get out of order, and it can be arranged to give an alarm in any desired locality, whether in a brnk, warehouse, police-station, or any other p ace.

I am aware that safes have been connected to alarm apparatus by electric wires, and therefore do not, broadly, claim such; but,

Having thus described my invention, what l claim, anddesire to secure byLetters Patent, 1s-

1. In a safe constructed substantially as described, the composition plates composed of water glass, alum, powdered burned clay, fresh or uuburned clay, and borax, as and for the purpose specified.

MAX KOLOSEUS.
